Two Mine Safety Monitoring Instruments Establishing Social Public Measurement Standards

Coal mine safety inspection capability is very important, and the measurement of mine safety monitoring instruments is equally important. Recently, two social public measurement standards, direct-reading dust concentration meter calibration equipment and oxygen detection alarm meter calibration equipment, passed construction standard assessment.

These two social public measurement standards were newly constructed and reported by the Metrology Center of Mine Safety Monitoring Instruments of Jiangsu Province. The successful evaluation of the standards means that the center will increase two social utility measurement standards to meet the needs of market testing and provide effective local specialty industries. Service.

The establishment of two measurement standards for the direct-reading dust concentration meter calibration device and the oxygen detection alarm calibration device is also of great significance for Jiangsu Province. This means that the detection capabilities of downhole dust and oxygen measuring equipment in Jiangsu Province have been further enhanced. The measurement capacity and technological upgrading of mine safety monitoring instruments in Jiangsu Province provide a safe and reliable environment for the development of local characteristic industries.

Shaft Damper

Slim Rotary Damper mainly used for small diameter, long height space. Shaft damper is used to dampen drives, control speed, and many other applications. Shaft damper are widely used in invisible screens. Shaft damper can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.
